What is FDM 3D Printing?
Fused Deposition Modeling (FDM) is a widely used additive manufacturing technology favored for its fast build speed, high dimensional accuracy, and low manufacturing cost. FDM equipment heats and precisely extrudes thermoplastic materials, building layer by layer to form the final part structure. Parts made with this process can be delivered in as fast as 1 day.
KH-TAT's FDM 3D Printing Services relies on the Stratasys Fortus industrial platform, offering build sizes up to 24" x 36" x 36" to meet large-format part manufacturing needs. We also support various general-purpose material options and can flexibly adapt to different FDM or FFF equipment for production.FDM process offers the richest color selection and production-grade thermoplastic system among all 3D printing technologies. Common materials include general-purpose ABS, ASA, and engineering plastics like high-performance polycarbonate and heat-resistant ULTEM, suitable for diverse scenarios from prototype validation to end-use parts.

What is Infill?
Infill is a characteristic unique to the FDM process. In FDM, an extruder nozzle deposits material along the toolpath, fusing it to previous layers to build a 3-dimensional body. The interior of the volume can be printed as “solid,” but it does not necessarily have to be. The pattern printed inside the contours is referred to as “infill.”
Infill can reduce material consumption and weight and allow for the production of confined volumes. An in-depth article on infill can be read here.
An Overview of the FDM Process
How Fused Deposition Modeling Works
With FDM technology, a spool of the chosen feedstock is introduced to a typical fused deposition modeling system via an extruder, which regulates the feed movement of the polymer to the heater where it melts. This molten polymer is extruded through a nozzle and deposited onto the print bed, also known as the build platform. The extruder, heater, and nozzle are all contained in a printhead, which is attached to a gantry above the flat build platform. This is designed to offer relatively high freedom of motion in the X and Y axes as the material is deposited.
The fused deposition modeling system uses innovative printer software to separate a 3D computer-aided design (CAD) file into individual slices, or cross-sections. Each slice in the file is converted into machine code, which essentially uses the Cartesian coordinate system to determine the path the printer head must follow across the X and Y axes to deposit the first layer of material onto the build platform. Once the bottom layer is complete, the build platform descends by a small amount – relative to the deposited layer thickness – and the printhead repeats the process to deposit the second layer. This procedure is repeated in sequential layers until the part is finished.
